HMmagnets Powerful Magnetic Vent Covers (3-Pack) – Upgraded Non-Slip Design for 7.25–8 in W x 11.25–12 in L Registers | White | Vent Not Included

Take control of your airflow with HMmagnets Powerful Magnetic Vent Covers

This 3-pack is designed to seal floor, wall, and ceiling registers within the 7.25–8 inch width and 11.25–12 inch length range. The upgraded design prioritizes a secure fit, quiet operation, and a clean, unobtrusive look in any room. While the vent itself is not included, these covers are built to complement most standard vents and help you tailor comfort across your living spaces.

Why choose these covers?

Real-life rooms often experience drafts, unwanted noise, and odors that travel between spaces. The magnetic system here uses hidden rare-earth magnets and a backside pocket to help the cover sit snugly over screws and dampers. The result can be a neater appearance with less draft, and a calmer environment where you notice the difference in comfort without the trade-offs of bulky, DIY adapters.

• Secure magnetic hold with a pocket design for an even, gap-free fit
• Blocks unwanted air movement while maintaining a low-profile look
• Reduces ambient noise and odors that can travel between rooms

How to select, install, and use

Before you buy, consult our size chart to choose the correct cover for your vent. Do not cut the cover; altering it may compromise performance and it won’t work if your vent size falls outside the listed ranges.

• Confirm vent width is between 7.25 and 8 inches and length between 11.25 and 12 inches
• Inspect your vent for a magnetic surface and place the cover over it for a snug fit
• Install in unoccupied rooms first to observe airflow effects in other areas
• Store unused covers in the included box for easy organization

In homes with multiple rooms or apartments, these covers offer a practical way to manage drafts, noise, and odors without permanent modifications. They’re designed to be easy to install in minutes, with clear instructions and a tidy storage solution for when you don’t need them.

What you get
